"wait, what's the joke? these two songs sound the same?" Can't things be funny without having a goddamn drumroll and a punchline just to tell you when to laugh? This is INSANE. Surely some part of you wanted to laugh seeing this.

That guy had a better idea. It's hard to hear on yours, but you have your synced up, especially since you chose a part with no lyrics.
What you SHOULD do is sync up the mp3 (not midi >:O) from Robo's theme up there and overlay that on the part he chose to play from Rick Roll.
